What is the average marks scored by all the students in Computer science?

Correct option is A

Given:

Marks scored by each student in Computer Science: A: 33, B: 39, C: 34, D: 41, E: 32

Total number of students: 5 Formula Used:

Formula Used:

​$$\text{Average marks} = \frac{\text{Sum of marks obtained by all students}}{\text{Total number of students}}$$ 

Solution:

$$\text{Sum of marks} = 33 + 39 + 34 + 41 + 32 = 179\\ \ \\\text{Average marks} = \frac{179}{5} = 35.8$$​​​
